Thepresent invention relates to transferrollsand particularly relates to' the'type of such rollsused" for applying an imitation or a simulationof wood grai'ning tometal si irfaces, such asgarnish moldings. 1 Y I 2. s

One of the primary objects of the-present in-- vention-isto provide a novel roller of the typementioned in which that; portion er the-Eroller" which engages-a metal surface of uneven or curved configuration readily conforms to the shape of such surface with substantially even force thereover.

Another object of the invention is to provide a novel transfer roll, of the type in which the periphery of the roll is applied to a metal surface, of such a construction that a predetermined variation in resistance to deformation of the periphery of the roll is provided and is dependent upon the shape of the metal-surface, so that the periphery of the roll readily conforms to the shape of the metal surface with substantially even force therecver. 1

Another object of the invention is to provide an improved roll of the type mentioned which is simple in construction and economical to pro i duce.

Other objects of the invention will become apparent from the following specification, the drawing relating thereto and the claims hereinafter set forth. I

Referring; to: the: drawing one. emhodiment: of; applicants invention is illustrated in whichthe roll is particularly adapted for applying .wood

graining ,to convex metal'surfaces. The wheel comprises a central hub portion formed of a pair of complementary sheet metal-stamping members In and I2. Such members are provided with aligned central openings M therethroughand. aresecuredtogether in facing relationby suitable means such as rivets lB." The. opening i is provided with a suitable keyway 3 so that the wheel may be readilyfixed to a suitable drive shaft.

The outer ends of members Ill and l2 taper outwardly as indicated atZBand terminate in It will be appreciated that in applying an imi- I I tation or a simulation of Wood graining to metal surfaces, such as garnish moldings, it is the practice to move a gelatinous roller over an engraved plate which has been engraved in simulation of a wood panel and which has had ink applied I surface to transfer or apply the ink thereon, reproducing thereon the imitation Wood grain finish. The metal surfaces on which the wood The gelatinous roller picks up the ink from the plate and is then rolled over the metal I gra'ining is applied are usually of relatively deep curvature, either convex orconcave; and with prior constructions the surfaces of the rolls do not conform properly to such curved surfaces so that best results are not obtained.

. According to the present invention the gelatinous sleeve or coating portion is backed up by a radially disposed annular riianges :22. wardlytapering or flared'portions 20 together with the flanges 22 form an annular seat within which an annular backing'r'nember 241s disposed. Such annular backing member 2 1 is of resilient sponge-like substance such as may be produced by a composition including glycerine, water and glue.

thereof. II I I An annular sleeve or coatingportion 26 is fixed to the peripheral surface of the member 25. Such I portion 26 is formed' of the conventional gelatin-" ous material used in rolls of the type.towhich the present invention is'direct'ed.

- a In use, the roll isapplied to the engraved plate I so that the peripheral surface of the gelatinous portion 25 is moved thereover. The wheelis then pressed-against the metal object towhich.

the wood graining is to be applied so that the curved surface thereof bears against the peripheral surface of the gelatinousportion 26.-

It will be seen that the backing member 24 is of variable depth transversely thereof so'that the I greatest depth of member 24 is at the transverse I center. The flared portions 20 which backup the member 24 provide a construction in -which The 'outp The member 24 is formed with a base portion which is generally complementary in shape to the space betweenflared'portions 2G. The sides of the member 24 extend radially be i yond the ends of the members I!) and 12 in sub- I stantially straight sides, and the outer periphery 1 of member 24 is substantially flat transversely the member 24' is more resistant to compression adjacent the sides thereof than at the center. It will thus be seen that when the roll is applied to a convex surface that the center of the roll may be compressed to a greater extent than the sides thereof so that the peripheral surface of member- 28 readily conforms to the convex sur face to which it is being applied with substantween said mountingportion and said peripheral portion, said backing portion varying in depth transversely thereof so as to present .difierent resistances to deformation across said peripheral portion. 7 a a a 2. A transfer roll comprising a. central mounting portion, an annular, e peripheral, gelatinous portion of substantially uniform thickness, said gelatinous portion having a cylindrical outersurface and a resilient backing 'portion disposed between said mounting portion and said peripheral portion, said backing portion being of difierent radial thicknesses transversely thereof so as to present different resistances to deformation across said peripheral portion.

8. A transfer roll comprising a rigid central mounting portion, a peripheral gelatinous portion of substantially uniform thickness, said gelatinous portion having a cylindrical outer surface and a resilient backing portion of spongelike material disposed between said mounting portion and said peripheral portion, said backing portion being of less radial depth adjacent the sides thereof than at the center thereof so that said center is less resistant to deformation than the sides thereof.

4. A transfer roll comprising a pair of sheet metal members fixed together to form a central mounting means, said members terminating in sides inwardly tapering toward the center to provide a backing sheet therebetween, a resilient backing member disposed within said sheet and being complementary in shape thereto so that said resilient backing member is of different radial depths transversely thereof, and a peripheral gelatinous member secured to the periphery of said backing member, said gelatinous member being of substantially, uniform thickness.
